Genuine BMW part 12 90 7 521 579: Bottom part. The number stamped on the part is 12907521579; BMW's catalog files it under the short number 7521579. You will find it on our Electrical shelf, under Other Engine Electrical System parts. BMW has since replaced it with 7534921.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

It weighs about 630 g (1.4 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
